Impact Changeability Analysis

Purpose

This tool helps prioritize a set of options.

Guidelines

1. Possible meanings of Impact and Changeability:
   
   

   Impact Considerations	Changeability Considerations
   Effect on quality	Resource requirements
   Time savings	Complexity of investigation
   Material Savings	Time required
   Morale	Ability to measure outcomes
   Number of people who benefit	Number of decision making levels required

   
   
   
2. Rank each option on impact and changeability using the following scales:

   If option were implemented (or problem eliminated) what impact would this have?

   • 1=Little Impact
   • 2=Some Impact
   • 3=Considerable Impact

   How difficult will it be to implement the option (or eliminate the problem)?

   • 1=Difficult
   • 2=Moderate Effort
   • 3=Little or No Effort
3. Use the chart below to determine the relative priority of the options. You may have multiple options that fall into each category.
